My company's 401k offers Wells Fargo funds. Today I got my Quarterly update and my question is, I am 24 years old and I want to go with as much risk as possible but the high risk funds that are available are Wells Fargo Index Fund,Wells Fargo Capital Opportunities fund(a),Wells Fargo Large Company Growth Fund (1), wells Fargo Small Cap Growth Fund (1), and Janus being the highest risk. I have read the fools advice on Index funds but in my Quarterly Report under there Performance it shows the Index Fund in 10 year being 13.91% the small Cap being 16.75% and it says underneith that Since Inception and Janus being 17.00% also under that it says Since Inception. My question is I am taking out only 4% out of my check and all of that is going into Wells Fargo Index Fund and I am wondering if I should leave it in there or should I put it somewhere else in the different funds I have listed.
